Wow!  Amazon/Target has the LeapFrog (Green) Tag Reading System for only $12.99 shipped!

That's a great price!! 

LeapFrog TAGÂ Reading System - Green



 My girls (4 and 2) love theirs, they each have one and it keeps them occupied and they have a blast.  My two year old has no problem using hers. 
  
I can't guarantee how long this price will last.  Amazon seems to be famous for raising/lowering prices within a few minutes time.  I have gotten in on a lot of fantastic prices for items, and missed out on quite a few too.
